Macerator pumps are used in sewage treatment to break down solid materials into small particles so that it is easy to drain them out of the tank.

These pumps use a grinding or blending mechanism in order to break down the solid waste so that they can be easily be pumped out of the system.

It is a piece of important equipment that helps in preventing blockages in your sewage and plumbing systems.

While we are traveling in our RV, we may or may not find a dumping station or find sewers that are higher than the holding tanks. In these situations, maceration pumps can be extremely beneficial in assisting with dump disposal.

There are different kinds of macerator pumps designed to suit different requirements.

Benefits of Having an RV Macerator Pump

Benefits of Having an RV Macerator Pump

Their small diameter hose also prevents the bad smell from penetrating the air around the RV and the campground.

RV macerator pumps make it extremely convenient to handle sewage, especially if the sewer is farther away or higher than your rig can handle. Macerator pumps are able to pump waste up any incline or any distance.

Handling and dumping water from your RV can be quite a messy job, especially when using the standard 3 sewer hose. It may also cause the bad smell from the waste to percolate in the RV and surrounding areas.

Macerator pumps help in alleviating these problems. They use a small diameter hose which does not allow the smell to permeate the air around the RV when the waste is being disposed of.

Types of RV Macerator Pumps

There are three types of RV macerator pumps that are used in an RV. These three include permanent RV macerator, portable RV macerator, and 110V RV macerator pump.

Portable RV macerator pumps are best suited for RVs that do not already have an inbuilt macerator. They are good for RVs that do not have an allocated area for a macerator pump.

They run in 12 volts of direct current (VDC) and can be used by simply hooking it up to the sewage tank.

Permanent RV macerator pumps are a good choice if your RV has a base installation setup. You can install the permanent RV macerator pump in those setups, and forget about it.

Sometimes these model are also available in a 115V model. The 115V model can be a risky choice as it may damage your rig. If you want to go for an AC-powered macerator, it is suggested that you go for a 110V option.

How do RV Macerator Pumps Work

How do RV Macerator Pumps Work

A macerator pump works with the help of a motorized grinder and pressure. They break down waste into small particles and then push them through a small hose to make it into a slurry liquid.

This can then be dumped into the dumping station or any private septic system as well.

A macerator pump works with the help of pressure rather than with the help of gravity like other standard sewer hoses. They are very similar to garbage disposal units that are so common in every household.

They are able to break down waste in two ways. Firstly, they use motorized grinders which, with the use of electricity, is able to break down waste into small particles, more like a slurry liquid.

After this is done, they pass this slurry waste through a small hose, which also with the use of pressure is able to make it smaller and more convenient for disposal.

Because the electric pump has done all the work, the process becomes extremely convenient for you.

All you need to do is empty this into a dumping station. Because the size of the waste has been reduced, you can even empty it in toilets, private septic systems, or even sewer openings. It will not cause any blockage.

Since the size of the hose is so small, it also helps in not letting the bad smell permeate through the surrounding air.
